A 120:480-V, 10-kVA step-up two-winding transformer is to be used as an autotransformer to supply a 120-V circuit from a 600-V source (a step-down autotransformer). When it is tested as a two-winding transformer at rated load, unity power factor, its efficiency is 97.9 %. 1.Show the connection diagram of the transformer converted as an autotransformer and identify which is the series winding Nse and the common winding Nc.

What is the KVA rating of the two-winding transformer after conversion as an autotransformer?
by Bartleby ExpertWhat is the rated current of the autotransformer at the low voltage side ( ILrated )? Note that the high and low voltage side of the autotransformer is 600 V and 120 V respectively.
